WATER MOTOR-DRIVEN VENTILATOR 2 SHEETS-SHEET 2 Filed July 26, 1947 7o 75 7 INVENTOR 7/ HARRY 'BAITHER 4 3 8% WI 7 am/g ATTORNEYS Patented July 22, 1952 UNITED STATES PATENT OFFICE This invention relates to ventilated toilets and is an improvement over my prior-patents, Nos. 1,931,052, 2,227,920 and 2,297,935 issued'resp etively to me October 17, 1933 January 7.1941 and October 6, 1942.

In these patents, I illustrated means for creating an air suction in the bowl of the toilets during the use thereof for eliminating objectionable odorsi My present invention appertains to meansflfor creating such suction by the use of a water motor or injector so as to eliminate the use of electric motors and the like. v

One of the primary objectsof my invention is toprovide novel water-seals or traps for the various conduits and pipes used in my ventilated toilet, so as to effectively preventthe passage of objectionable vapors from the bowl and sewer pipe to the flush tank.

Another salient object of my invention is to provide means, for emptying the water-seals while the water motor and suction fan is in operation 'and for automatically replenishing the seals with water when the toilet is not in use.

A' further important object of my inventionis the provision of means for automatically supplying water tothe water motor as soon as weight is applied to the toilet seat, whereby the, suction fan will be immediately set in operation.

With these and, other objects in view, theinvention consists in the novel construction, arrangement and formation of, parts as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings,

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the

letter T generally indicates my improved ventilated toilet and the same comprises a toilet bowl to having communicating therewith, through a water basin or trap II, a drain pipe I2.

The upper end of the bowl I0 has formedtherein a flush ring I3. Formed'in the flush ring I3 is a plurality of outlet apertures I4 and-the flush ring communicates with the main water outlet I 5 of the flush tank I6. This outlet I5 communicates with an enlarged passageway ll of the bowl I0; The flush tank 16 can be formed integral with or separate from the bowl l9.

Theoutlet I5- of the tank can becontrolled by any preferred type of valve I8. Communicating with the outlet passage I5 below the valve'l8 is an upright over flow pipe I9. The upper-end of this pipe, in accordance with my invention is flared to form a valve seat ZB'WhiCh is normally closed by a float valve 2|, Depending from; the float valve 2| is a weightedvalve guide stem 22. If the water in the tank I6 rises above the over flow'pipe the valve 2| will float off of its seat and allow the water to drain into the pipe I9 and thence into the toilet bowl. Under normal con ditions the valve 21 closes the overflow pipe against theadmittance of water and air.

The valve I 8, utilized for controlling the flow of water from the tank I6 to the bowl can be operated in anydesired way.

Extending into the tank I6 is a main water supply pipe. 23 and this pipe is provided with ,a valve 24' which is automatically operatedby a pivoted float 25. When the float.25 lowers, the valve is opened so as to admit water to the tank and when the float valve raises with the water in the tank acertain distance thevalve is closed. This is in accordance-with-the usual practice and forms no part of my present invention.

In order to create the suctionv in the bowl through thering I3 I templo y arotary suction ing a modified ,form of the water replenishing means in which thevacuum floatbreakeris eliminated. I a g Figure 6 is a fragmentary detail vertical secfan ztr This fan includes acasing ZI and a, rotaryian blade 28 mounted upon-a shaft-29., I Theinlettil-of the fan casing or housing jl has communicating therewith an air. intake. con

duit pipe ;3 I and thelower end of this pizza comr; municates with the overflow pipe I9 adjacent to its lower end. Consequently when the fa 26 is in operation, air will be sucked in from the overflow pipe |9 into the fan casing and air will be drawn by the fan from the bowl through the ring l3. Obviously, the valve 2| prevents the sucking "of air from the tank IS. The outlet of the fan casing 21 has communicating therewith an exhaust pipe 32 and this pipe can be In order to operate-the suction fan 26, Iutilize awater driven motor 35. This motor can be of the turbine type and includes acylindrical casing 36. y

v The casing forms bearings for the shaft 29 and the shaft has secured thereto a turbine wheel 3|.v 'As illustrated, one end of the cylindrical casing can be provided with a wear take-up screw and an antifriction ball 39 can be disposed. between the adjacent ends of the shaft 29 and the screw 38. Communicating with the water motor casing 36 is=a water inlet pipe 40 and this pipe can lead to any suitable source of water supply. The pipe 40 extends through the bottom of the flush tank l6 and has connectedtherewith a valve 4| for controlling the flow of water through the pipe to the water motor. The valve 4| is of the poppet type and is provided with a depending operating stem 42. When thestem is pressed upwardly, see Figure 1, thevalve will be open to permit the flow of water through the pipe. To push up on the stem, I provide a lever 43 which is rockably mounted intermediate its ends on a pivot pin 44 carried by-a bracket 45. The bracket is secured in place in any desired way. The rear end of the lever extends under the stem 42 and the front .end of the lever extends under one of the sliding brackets 46 which hingedly support, as at 41, the toilet seat 48. The brackets 46 are normally held in a raised position by expansion springs 49.. When weight -is placed on the seat 48 the brackets 46 will be lowered against the tension of the springs 49 and the lever 43 will be actuated to open the valve 4|. When pressure is relieved from the seat the lever will resume its normal position and the valve 4| will return to its normal closed positon by the weight of the valve body or'by spring means. Obviously this .valve 4| can be of an ordinary well-known type.

The outlet 50 for the water motor 35 is arranged on the opposite side of the turbine wheel 3'! from the inlet water pipe 40'. This outlet 50 communicates with a water discharge conduit pipe The lower end of the pipe is connected as at 52 to the air discharge conduit pipe 32. A water trap 53 is formed in the water discharge conduit pipe 5| so as to prevent the back flow of, gases through thispipe; V

The pipe 5| extends through the upper end of an upright casing 54 utilized for replenishing certain seals and traps with water and the pipe 5| isfprovided with a small openingf55 toallow the flow of water therefrom into said upright casing.' Thelower end "of the upright casing 5 4 has connected therewith a tube 55 which leads to the water-seal and trap 34 of the air exhaust conduit pipe 32., When water is flowing through ward into the tank.

4 the pipe 5|, water dripping through the opening 55 will flow into the upright casing 54 and the upper end of the casing can be provided with an air opening 51. If preferred, a float 58 can be arranged in the casing5'4fbetween the pipe 5| and the top wall of the casing; When the casing is filled with water, the float 58 will rise and close the air opening 51 and prevent the escape of air from the casing. When the water falls, the float 58 will move away from the opening 51 to allow the entrance of air and break any vacuum which might occur in said casing. As illustrated in Figure 5 the upright casing 54 can merely be provided with a guard 59 to prevent splashing of water in lieu of the float and the splash guard 59 is so arrangedtodirect any water flowingthrough the opening 5? down- The trap 34 of the air exhaust conduit pipe 32 is preferably provided with a water drain pipe 60 at its lower-most point. 1

This drain pipe is of the siphon type and is of an inverted U shape and has the long leg communicating as at 6| with the water dis? charge pipe 5|. 1

Considering that the trap 34 and the trap 53 are filled with water and the seat 48 is lowered by a user, then the valve 4| will be opened and water under pressure from a water main will enter the motor casing 36 and drive the turbine wheel and this water will flow. out of the, pipe 5|. The flow of water through the pipe 5| will create a suction in the siphon tube 60' and will drain out the water from the trap 34r The rapid rotation of the turbine wheel will operate the fan 26 and cause the intaking of air from the bowl I0, through the ring |3, chamber overflow pipe l9, and pipe 3|. The exhaust air will now flow through pipe 32 and the air under some pressure will tend to carry any trapped water from the trap 34 to the sewerpipe. It being understood, that most of the water orall of the water in the trap will be siphoned off by the siphon tube 60. The water from the water motor will be carried to the lower end of the pipe 32 by the discharge pipe 5| and the up-. right casing will receive water therefrom. 'As soon as weight is removed from the seatand the fan 26 stops its operation the water flowing from the upright casing through'tube 56 will refill the trap 34. I I

It therefore can be seen thatI have provided novel means including a water motor for effectively removing objectionable odors from a toilet bowl. The entire ventilating means is so .arranged and constructed as to meet with .the approval of the underwriters. I

As in the usual construction of toilets for flush tanks, I can provide a refill tube 62 for the bowl I 0 after the flushing of the toilet. This refill tube communicates with the upper end of the water supply pipe 23 and enters into the overflow pipe I9. The refill tube is provided with a water trap 63 and an air opening :64 adjacent to its upper end. J I,

In Figure 6 I have illustrated a slightlyinodified form of my invention and I have found, in communities where water pressure is suf-j eliminated the ',showing of this siphon. tube.v Where'the water pressureis suflicient, the flow of water through the outlet pipe 5| will beof such force as to create a suction in the pipe In: lieu of providing the floatvalve. 2l, I can provide awater trap 65 for the over now pipe I Asillustrated in Figure ti, the overflowpipe I9 is divided and includes, anupright section --6.6".;and a-short section 6'! which communicates {with the outlet'l5,' below,the}.flush valve l8.

The upper end "or the pipe 6"! extends into the water trap casing 69 above the normal Water level thereinand the upright :section 66 extends into the trap casing 69 below the water" level. The air intake pipe 3| instead of communicating directly with the overflow pipe, connects with the upper end of the trap casing 69. Consequently air will be only drawn from the bowl and in through the short section 61 of the overflow pipe.

In Figures 8' to 9 inclusive I have shown another form of my invention in which an ejector or siphon jet I can be utilized for creating the desired suction in the toilet bowl.

The injector can be in the nature of a T coupling H, the longitudinally aligned legs of which can have coupled thereto the water supply pipe 12 and the water outlet pipe 13. The inner end of the water inlet pipe 12 is provided with a nozzle 14, which points toward an intakehead 15 carried by the inner end of the water outlet pipe '13. Communicating with the other leg 16 of the T coupling is the air intake suction pipe 11. Obviously, when water under pressure is flowing through the pipe 12 and forced through the fine nozzle 14 into the pipe 13 a'draft or suction will be created in the ejector so that air from the pipe 11 will be forcibly sucked from the pipe 11.

In Figure 8 the flush tank is indicated by the reference character 18 and the ejector I0 is cated in said tank and the pipe 11 communicates with the overflow pipe 19 of'the tank. The overflow pipe can be normally closed by a float valve 80 of the same type as shown in Figure 2. The pipe 1'! is provided with a water trap or seal 8| so as to prevent the flow of objectionable vapors therethrough. The pipe 13 carrying the exhaust water and the objectionable vapors is tapped into the sewer pipe in the same manner as conduit 32 shown in Figures 1 and 2. The water supply pipe 12 receives its source of supply from a water main or the like through water inlet pipe 40 and is provided with a water seal or trap 82. This pipe passes through an upright casing 83 which corresponds to the upright casing 54 and the pipe at the point where it passes through the casing 83 has a water drip opening formed therein so that water will be supplied to the casing. The lower end of the easing has a water supply tube 84 leading therefrom to the water trap 8| so that this trap will be supplied with water. The trap 82 has communicating therewith, above its U bend, a pipe 85 and this pipe in turn communicates with the water drain 13. Communicating with the pipe 85 is a siphon tube 86 and this tube communicates with the lower end of the trap 8|. Consequently when water is flowing through the pipe 85 a suction will be caused in the siphon tube to permit the withdrawal of the water in said trap 8|. When my apparatus is in operation, water will be withdrawn from the seal 8| to allow the withdrawing of the vapors from the bowl through the overflow pipe 19, pipe 11, into pipe 13.

, "6 'j Wherewater pressure is great enough. to cause sufficient 'suctioninpipe 11 to withdraw: the water from the trap Bl', the siphon tube 86*can be eliminated. V i

The flow of water'through the :pipelZ is controlled by a: valve in'the'same manner as' the pipe 40 is controlledbyl the valve 4'! inFigures -1 and 2 of the drawings Other 'changeslin details can be mad without departingfrom thespirit or the scope of my invention, but What I claim asnew is, 1. A ventilated toilet comprising a bowl having apwater basin therein and a: drain pipe below motor for operating the fan, said water motor.
